Add back per player mob spawning

Browse Source 
Also removes the `info.mobCategoryCounts.mergeInt` call that - at least from what I can tell - has been wrongly counting spawned mobs twice. The runner passed via `info::afterSpawn` already counts up that exact number in the same exact places (where `j`, the return value used here, is incremented)
